I have no issue with the work they did, but they should routinely carry cleaning equipment such as brooms, dustpan and brush and a vacuum cleaner. They should not need to use mine, or ask me for a bucket to mix up plaster in. Finally they really should take their rubbish away or tell their clients the price does not include rubbish removal. Putting it in my neighbour’s bin and on my garden is unacceptable.

Delighted with the service received from this company. Completed the job to quoted budget and well within the maximum timeframe quoted including doing some extra work (painting hallways, replacing spotlights) that weren't in the original job. Everything looks really good, and I wouldn't hesitate to recommend them.

Absolutely thrilled with our new shower! Amir was fantastic—professional, friendly, and nothing was ever too much trouble. We had a radiator changed, another one removed, a boil tap installed, and our bath taken out and replaced with a sleek new shower. Amir and his team were brilliant throughout, keeping everything tidy and treating our home with great care.

Krzysztof did a great job fitting 2 showers, decorating ensuite, changing all the taps and 2 showers, and doing a number of small fixes and improvements in the flat. I appreciate his clear and detailed communication on job needed, options provided, and consulting on fittings and materials. He finished the job with high quality and with just a small delay despite of a good amount of obstacles (we did painting in parallel). Would definitely recommend Chris's services!

The job was to cut back a severely overgrown patch of garden. Chris & his team, Adrian & Cosmin, gave me a competitive quote, after coming to visit the site to assess what needed to be done. They started next day and completed the job quickly and to my complete satisfaction. The site was cleaned up & all waste taken away. I will definitely use them again and strongly recommend them.

Great serivice by Dorian, he was greatly helpful to understand my objectives for the works needed and the deadlines I had to achieve those. He's spot-on for electrics, but he was outstanding on all-round trading works, excelling also on painting, flooring and plumbing, even if a fully busy schedule during the working week and thus committing flexibly during his extra time on evenings and weekends. Hope to works with him soon again on bigger projects!
